Microsoft Certified: Azure Fundamentals (AZ-900) Practice Exam

What type of service does not require you to manage the application?

1. A SaaS

2. B PaaS

3. C On-Premises

4. D IaaS

The correct answer is: A SaaS

The correct choice is a Software as a Service (SaaS) solution. SaaS is a model where the service provider manages everything related to the application, including the infrastructure, platform, and application itself. Users can access the software via the internet, typically on a subscription basis, which allows them to focus on using the application rather than overseeing its maintenance, updates, or deployment. In contrast, Platform as a Service (PaaS) may require some management of the application, particularly regarding the environment and resources used for application development and deployment. On-Premises solutions necessitate full control and management by the organization, including hardware and software maintenance. Infrastructure as a Service (IaaS) allows users to manage virtualized computing resources over the internet, but it also involves managing operating systems, applications, and middleware. Thus, with SaaS, the user is relieved of any application management responsibilities.
